Warning Symbols
This symbol indicates information that, if ignored, could result in minor injury or
damage to the equipment.
This symbol indicates information that, if ignored, could result in serious injury,
damage to the equipment, or death.
This symbol indicates information that is important but not hazard-related.
Warnings
Read this entire document before installing or using the Sol-Ark 15K inverter. Failure to follow any of
the instructions or warnings in this document can result in electrical shock, serious injury, or death.
Damage to the 15K inverter is also possible, potentially rendering it inoperable.
High Life Risk Due to Fire or Electrocution – ONLY qualified persons should install the Sol-Ark 15K
inverter.
The system must have Ground connections and Neutral connections. Ground MUST be bonded to
Neutral ONLY ONCE in the circuit.
Solar PV+/PV- are UNGROUNDED. Note, you may ground PV Racking/Mounts, but doing so directly
to the Sol-Ark will likely result in damage in the case of a direct lightning strike to the PV array.
DO NOT connect the grid to the Load Output Terminal Block.
DO NOT reverse the polarity of batteries. Damage WILL occur.
DO NOT exceed 500Voc on any MPPT on the Sol-Ark.
DO NOT turn off the battery breaker if there is current flowing into our out of the battery in any
amount.
DO NOT use impact drivers to tighten any fasteners on the Sol-Ark.
MUST use Strain Reliefs ON ALL wires entering/exiting the Sol-Ark 15K user area.
MUST use conduit (or double insulated wire) for AC Wires entering/exiting Sol-Ark 15K user area.
ALL terminals/breakers, including battery, MPPT, and AC Terminal Block inputs, should only have
one conductor connecting to them.

D. WI-FI Dongle Input J. MPPT Inputs
E. 2 x 200A Battery Breaker K. Neutral/Ground Bus Bar
F. Communication Ports L. Terminal Blocks (GEN/ Load/ Grid)
Deciding Backup Circuits
A. Ensure you keep the inverter within its amperage limits
• ON-Grid = 200A Continuous (pass-through)
• OFF-Grid = 12kW = 50A Continuous (62.5A w/ solar) | 24kW = 100A Peak (10s) | 30kW = 125A Peak (100ms)
B. Verify each load circuit by measuring typical and max Amps with a clip-on Amp meter. Amps x 120V = Watts
C. Install a subpanel for backup loads if there is a chance of exceeding any amperage limits while powering the
entire home off-grid; failure to do so will result in an outage and potential damage to the inverter (see pg. 12).
D. If you have Arc-Fault / GFI breakers, DO NOT use a multi-circuit transfer switch.

Single System Installs (Whole-Home Backup)
A. Use the output from 200A Fused Disconnect (from the grid) for the Grid input connection to the Sol-Ark
B. Connect the Load output from the Sol-Ark directly to the Main Service Panel (at least 2/0 AWG)
C. Connect a Generator (100A) or AC-Coupled system to the GEN terminal block
Mounting the Sol-Ark
A. Keeping in mind Sol-Ark's dimensions, find a suitable location for the system(s)
B. NEMA 3R rating for Outdoor installations
C. PROTECT the LCD screen from excessive UV exposure
D. System weight = 135lbs (61.24kg). Securely attach to the wall. Affix a mounting board to studs using 6-8 screws
E. Use 2-3 screws + washers (choose screw length and surface type) to mount the French Cleat to the board/wall
F. Mount Sol-Ark on the installed French Cleat / Ensure Sol-Ark is level and sits properly
G. Add two screws for the bottom mount
Integrating Batteries (Sol-Ark POWERED "OFF")
A. Connect batteries to Sol-Ark as shown in Fig. B below
B. Install included toroids (Part e. on pg. 4) on battery input cables, as shown in Fig. A to the right
C. Ensure the built-in battery disconnect is OFF while connecting batteries, or arcing may occur
D. The 15K reaches a max of 275A of battery charge/discharge if using both sets of battery
terminals. If using one set of terminals, the max battery charge/discharge is 160A. (see pg. 21)
Multi-System Installs
a. ALL paralleled systems MUST connect to the same large battery bank, each with its own
cables attached
b. Do NOT use separate battery banks for parallel systems
Positive to
Sol-Ark
Negative
to Sol-Ark
Sol-Ark 15K is a 48V system. Do NOT wire
the battery bank to any other nominal
voltage.
When using 12V batteries do not exceed
FOUR (4) batteries in series.
When using other battery chemistries, stay
within the voltage range: MIN 43V-MAX 63V
Fig. A
Do NOT stack more than 2
banks high
PCC batts are
stackable
Do NOT reverse
polarity of batteries!
Damage will occur!

Connecting Solar Panels
A. Sol-Ark has TRIPLE MPPTs for three separate PV input pairs
B. MAX PV input = 19.5kW (± 5%) / system | 6.5kW / MPPT | MAX 500VOC PV | MAX ISC /MPPT 26A (limiting to 26A)
Damage will occur if PV VOC > 550V
C. Parallel strings per MPPT must be the same Voltage
i. PV1 A/B must be the same voltage if using both strings
ii. Panels on the same MPPT CAN face different directions
D. GND the panel MOUNTS/FRAMES to any GND outside the circuit via 12AWG wire
E. IF using Y-Connectors: Running two strings in parallel, totaling 26A (self-limiting)
F. Connect the solar panel strings as indicated by the following diagram:
G.
Only one temperature sensor
can be used per install
(Connected to Master Inverter)
Check Battery Integration Guide for specific
instructions on Closed Loop Comm
Integration: www.sol-ark.com/support/
Each string can use separate
wires
String minimum is usually 5
panels or 125V
Maximum combined Input
(AC+DC) = 38.7kW
19.2kW AC Coupled +
19.5kW DC Coupled
Multi-Terminal Multi Lead Acid Install
Multi-Terminal Multi Lithium Install
Optional Battery Installation Method: Multi-Terminal Installation
The battery terminals parallel batteries to ensure a common connection. If 275A charge/discharge rate is needed,
connect batteries to both terminals; If using 3 or more batteries, use a busbar for + and - battery connections.
Only connect batteries of the same brand, model, and chemistry to both terminals. if Lead Acid, approx. age also.
Multi-Terminal Single Battery Install
You will only need to do a multi-terminal
single battery install if your single battery
has a max charge/discharge current >160A.
